Edinburgh palaeontologist says smaller mammals are better able to cope with increased temperatures
The climate crisis may lead the human race to shrink in size, as mammals with smaller frames appear better able to deal with rising global temperatures, a leading fossil expert has said.
Speaking to the Guardian before the publication of the book, Brusatte said that becoming smaller was “a common way that mammals deal with climate change”. He added: “That’s not to say every species of mammal would get smaller, but it seems to be a common survival trick of mammals when temperatures spike pretty quickly. Which does raise the question: if temperatures do spike really quickly might humans dwarf, might humans get smaller? And I think that’s certainly plausible.
over the past million years have also suggested that temperature is a major predictor of body size variation, while scientists studying red deer have said that warmer winters in northern Europe and Scandinavia may lead to the body size of these animals becoming smaller.that rising temperature causes mammals to shrink.
